The invention relates to a method of sealing an ultrahigh-pressure test container. The method comprises the steps that a high-pressure test container cylinder body is vertically fixed, the sealing surface of a sealing head is installed in an inner hole of the high-pressure test container cylinder body, a lifting bolt is screwed in a threaded hole in the upper end, a threaded pressing ring is rotated by a wrench, and the rotation is stopped until the gap between the lower end face of each fan-shaped groove of the threaded pressing ring and the upper end face of the corresponding fan-shaped tooth of the sealing head is 4mm to 5mm; the threaded pressing ring is rotated reversely, and the situation that the fan-shaped teeth of the sealing head are consistent with the fan-shaped grooves of the threaded pressing ring in position is guaranteed; the lifting bolt is lifted, the sealing head is pulled out, and O-shaped sealing rings are installed into annular sealing grooves; then the sealing head is pressed into the inner hole of the high-pressure test container cylinder body until the gap between the lower end face of each fan-shaped groove and the upper end face of the corresponding fan-shaped tooth of the sealing head is 3mm to 4mm; and the threaded pressing ring is rotated in the forward direction so that the fan-shaped teeth of the sealing head can deviate from the tooth grooves of the threaded pressing ring by 30 degrees, and sealing is accomplished. According to the method, the internal and external double-sealing mode is adopted by the ultrahigh-pressure test container, disassembly is convenient, the installation efficiency is high, the sealing performance is good, and the repeatability is good.
本发明涉及一种密封超高压试验容器的方法,高压试验容器筒体直立固定,密封头的密封面装入高压试验容器筒体内孔中,上端螺孔旋吊环螺钉,用扳手旋转螺纹压环,旋转至螺纹压环扇形槽的下端面与密封头扇形齿的上端面间的间隙为4‑5mm时,停止。反向旋转螺纹压环,保证密封头的扇形齿与螺纹压环的扇形槽位置一致;起吊吊环螺钉,拔出密封头将O型密封圈装入环形密封槽中;再将密封头压入高压试验容器筒体内孔中,直至扇形槽的下端面与密封头扇形齿的上端面间的间隙为3~4mm。正向旋转螺纹压环,使密封头扇形齿与螺纹压环齿槽偏移30°,密封完毕。本发明对超高压试验容器采用内外双重密封方式,拆卸方便,安装效率高,密封性好,重复性好。
